I agree with most of the other posters here:

These engines are subject to sludging problems, high oil usage and plugged crankcase ventilation systems. Using correct oil will help you avoid these problems. Using dino and long oil change intervals and you will have them.

If you can swing it - look for a synthetic oil that has BMW LL01 approval or at least A3. They do come on sale occasionally.

German Castrol 0W30, M1 0W40 and BMW 5W30 are some commonly available LL01 oils. I recently got some old formula (red jug) Maxlife full synthetic 10W30 on sale with LL01 approval and I am very happy with the results so far.

If you have to use dino I would use a 15W40 and change the oil every 5,000 miles. Or, if you are going to use a cheaper synthetic go with a 10W30 rather than the 5W30.

I say sell the car. If you are THAT concerned about a simple oil change then I would really like to see your face when you need to do brakes. BMW's like most european cars ( VW excepted) are designed to wear down the rotors as the brakes wear. They WANT you to replace the rotors AND pads when you do brakes.. Typical german thinking of which I fully agree with. Cost? a LOT more than an oil change.


get yourself a nice toyota corolla and bank the change from selling the beemer.

I was honestly thinking the same thing. If the OP wants to save money (nothing wrong with that), then he could potentially save a whole lot more by trading the 3-series for a KIA - no need for synthetic, no need for premium gas, better mpg, smaller sump, and still gets you from A to B.

While BMWs aren't particularly expensive to maintain if you DIY, they can wreck havoc on your pocket if you don't DIY. Taking it to a shop like Jiffy Lube is risky, and most reputable indy shops will charge upwards of $80/hour for labor (which is still a lot less than what a BMW service dept charges). Plus, OEM parts can be pricey.

Beat me to it. As for brakes, I've had the front brakes/rotors replaced twice, and the rear once. The first time, the dealer told me it was $1200 parts/labor. Lucky me, the car is still under warranty.

This doesn't necessarily relate to the OP - but don't you know there are a lot of folks that push the edge of their wallet and buy a semi-exotic car, not knowing that they're then going to get fully reemed out on maint. cost.

Not sure if the OP's car came with the sport pkg, but if it did, add to that the cost of low-profile tires. And this is not strictly a BMW thing. A lot of folks go for large rims, low profile wide tires these days, and then get a shocker when it's time to replace them.

And if the tires are runflats, oh boy....

Well pete.. Its like this, you can do the math in several ways and I guess regular oil is still going to be cheaper but not by much. So i get that now.

And no I dont run my car on premium. I run it on regular gasoline as I read in a yahoo article and in readers digest that most cars made after the 90's have fuel sensors which can detect what ever gasoline gets put in to the vehicle. So in the olden days it was true putting in the wrong type of gasoline would cause engine knocking but with fuel sensor technology that is no longer true. I've been using regular gasoline since last november and havent noticed any problems or symptoms of engine knocking. So i assumed what I read was true. Am I wrong on this?

QOUTE BY GARY--->Nobody mentions an oil like RTS 5w-40. While it won't meet all the Euro spec's ..it should be able to handle what the engine throws at it and have decent longevity in service.

What does RTS stand for? RTS 5w-40 is mineral oil... how much does that go for? How often should that be changed. Just want to collect information on that.

How is using regular oil cheaper?

Say you do 10k miles a year - that's one oil change using synthetic or two oil changes using mineral.

Cost of synethetic oil change - $100, as you noted. I'm guessing about $60 of it is materials, $40 labor.

Cost of mineral oil change - about $30 for materials (using quality mineral oil) and again that $40 labor, so $70 total; $140 for the year.

Not only is the mineral route more expensive, you also waste twice as much time.

You're right that it's not going to cause problems, but your reasons for doing it are flawed. You're probably thinking you're saving money by running regular. You are not.

Because the engine adjusts timing based on lower octane gas, two things happen:

1. the car's performance is negatively affected
2. the car consumes more fuel

So, there go your savings.

Now, I know you will say that you don't notice any difference in performance. In which case we go back to the previous question: do you notice any difference between driving a BMW and a KIA? If not, again, there is a potential for you to save a lot more money there.

Shell Rotella T Synthetic. There are no 5w-40 mineral oils.

It's about $20 for 1 gallon. You would need 2 gallons for an oil change. It's good oil, but doesn't carry BMW approvals (either because it doesn't meet their specs or wasn't tested for it).

But for about $40, when on sale, you can also buy 7 quarts of synthetic oil that does meet BMW spec, so I'm not sure if RTS is such a great deal here.

Okay you just said BMW engines are more prone to sludging problems.. why is that? Why does it consume more oil, etc. So why is synthetic oil more able to combat sludge, I read on company websites(valvoline, castrol,etc.) that both their mineral and synthetic oils have detergents that prevent sludging. So do mean to say synthetic oil has more detergents than regular oil.

why is 15w40 dino better than 5w-40 dino grade? 5w-40 will break down alot faster?

I really would like to learn how to change oil on my own car, thought of taking a few auto shop classes at my local community college...thanks for the encouragement Rusty. If u were near by i would definetly take u up on your offer with out thinking twice lol. I will look into the price of some of these tools.

Changing oil on this car is a piece of cake. You don't need any classes. Buy yourself an oil extractor - it's about $50. You suck out the old oil from the top through the oil dipstick. You replace the oil filter and filter gasket from the top (with a 36mm socket). You pour the new oil in. You take the old oil (in the extractor) back to an auto parts store. And you're done.

This car is by far the easiest one to change oil/filter on.
